国家地下水监测工程数据在地下水动态月报评价中的应用效果浅析

Application of National Groundwater Monitoring Project Data in Monthly Report of Groundwater Dynamics

地下水动态月报是水利部门定期发布地下水情的重要平台之一,传统的地下水监测数据收集方法使得月报发布存在滞后明显的现象。国家地下水监测工程(水利部分)的建设为月报编制工作提供了更加及时、覆盖面更广的监测网络和数据信息。选取江苏北部平原区与辽宁中部平原区为代表,对比分析了国家地下水监测工程监测数据与传统人工上报地下水数据,定量描述了两类数据表达区域地下水埋深空间分布特征的差异。研究表明,国家地下水监测工程的地下水监测站点分布和数量要优于历史人工测站的分布情况。

The monthly report of groundwater dynamics is an important production showing the groundwater regimen in the main plains of the North China released by Ministry of Water Resources.The traditional method of manual collecting made serious delay of the monthly report publication.Parts of the national groundwater monitoring project,constructed by Ministry of Water Resources,provide a more extensively monitoring network and timely groundwater monitoring data.In this paper,the northern plain of Jiangsu and the central plain of Liaoning were selected as two cases.The two kinds of data sources of the monitoring data collected from the national groundwater monitoring project and the traditional method were comprehensively analyzed,and the differences in the spatial distribution of the groundwater depth were quantitatively described.This research shows that the spatial distribution and quantity of the groundwater monitoring stations in the national groundwater monitoring project are better than those derived from the manual stations.
